Technical Field

The invention relates to the field of medical instruments, in particular to a gas injection device for laparoscopic surgery.

Background

In the process of a laparoscopic operation of the urinary surgery, part of the operation is carried out in a posterior abdominal cavity or an extraperitoneal cavity, and in the operation area without the space cavity, the posterior abdominal cavity or the extraperitoneal cavity is required to be opened and established by a method of manually injecting an air bag when the operation is started, so that the next operation is better carried out.

At present, most of the posterior abdominal cavities or the abdominal cavity external gaps are established by manually self-making expansion air bags, the air bags are usually sleeved on an expansion air bag pipe by a middle finger or a palm part of a medical glove, then are fastened by a silk thread, and then are injected with 1000ml of 600-fold air. In the process of gas injection, because the gas injection is a one-way pipeline, two operation participants are generally needed to coordinate to complete the gas injection in order to prevent gas backflow. In each air injection process, a first operator firstly uses an injector to extract air, the air is injected into the expansion air sac tube in a pressurizing mode, after the air injection is finished, another operator rapidly clamps the expansion air sac tube by using vascular forceps, the expansion air sac tube can be a drainage tube or a catheter to prevent air in the expansion air sac tube from flowing back, the first operator extracts air again to start the next air injection operation, and the air injection operation needs to be repeated for 10-20 times. The operation space is generally established from the production of the artificial balloon to the insufflation, which takes about 10 to 15 minutes.

The existing method for establishing the operation space and the used instrument have the following defects: 1. wasting manpower and time of the operator; 2. when the traditional method is used for injecting gas, two operators can cause inaccurate gas injection amount if the operators are unskilled in the matching process; 3. the patient is now under anesthesia, which prolongs the time to establish the operating space and increases the risk of the operation due to the prolonged operation time of the patient.

Disclosure of Invention

The invention aims to overcome the defects in the prior art and provides the gas injection device for the laparoscopic surgery, which reduces the manpower, shortens the operation time, and has simple process and low cost.

The technical scheme adopted by the invention for solving the technical problems is as follows:

a gas injection device for laparoscopic surgery comprises a three-way gas injection pipe, wherein the three-way gas injection pipe comprises a gas injection pipe body;

the gas injection pipe body is provided with a first opening, a second opening and a third opening;

the first opening is provided with a first gas check device which is used for connecting the expansion air bag pipe;

the second opening is provided with a second gas check device which is used for injecting gas into the gas injection pipe body;

the third opening is used for connecting a suction device.
